Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a fire-extinguishing shape holding hose used in a fire hydrant device installed in a tunnel or the like.
[0002]
[Prior art]
Conventionally, as this type of fire-extinguishing shape holding hose, for example, there is one shown in FIG.
In this conventional shape retaining hose 100, the hose body 101 is constructed by covering the inside and outside of a cylindrical jacket woven with warp and weft yarns with a rubber material, and further reduces friction on the outside of the shape retaining hose body 101. Therefore, it has a structure in which a low-friction coating 102 such as a polyester woven fabric is covered, and the resistance is reduced as compared with a shape retaining hose covered with rubber.
[0003]
[Problems to be solved by the invention]
However, in such a conventional fire extinguishing hose for fire extinguishing, for example, when the hose is drawn out for a very long length of about several tens of meters, the weight of the hose itself and the weight of the fire extinguishing liquid inside are required. As the frictional force increases, a large pulling force is required, and the nozzle cannot be quickly brought to the desired position.
[0004]
In addition, the hose has been reduced in weight by using foamed rubber as the rubber material, and the hose has been devised to cover the hose with a low-friction material. In this case, there is a problem that a considerable drawing force is still necessary due to the weight of water in the hose being increased and the friction coefficient being limited.
[0005]
An object of the present invention is to provide a fire-fighting shape retaining hose having a structure that greatly reduces the hose pulling force.
[0006]
[Means for Solving the Problems]
In order to achieve this object, the fire retaining shape holding hose of the present invention is characterized in that part or all of the surface of the shape retaining hose body is covered with brush-like flocks. Thus, by covering all or part of the outer surface of the shape-retaining hose with the material planted in a brush shape, the present invention makes the sliding motion of the hose at the time of drawing out a ciliary motion. The drawing force is reduced, and even a long hose can be pulled out and moved with a small force, and a long hose can be stored with a small force.
[0007]
You may make it cover the shape-retaining hose for fire extinguishing of this invention spirally with the brush-like flocking of the surface of a shape-retaining hose main body. Moreover, you may make it cover the part or all of the surface of the shape-retaining hose main body with resin or cloth planted in the shape of a brush.
[0008]
The brush-like flock used for the fire-fighting shape-retaining hose has a thread shape with a cut end or a loop shape. Further, the brush-like flocking has a strength that does not buckle due to the weight of the shape-retaining hose body filled with fire-fighting water. Furthermore, the main purpose of the fire retaining hose is for a fire hydrant.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a cross-sectional view of an embodiment of a fire-extinguishing shape holding hose according to the present invention. In FIG. 1, a shape-retaining hose 1 of the present invention forms a shape-retaining hose body 2 by providing a rubber layer 5 covering the inside and the outside of a cylindrical jacket woven with warps 3 and wefts 4. In this embodiment, a flocked resin layer 6 is provided which covers the entire surface of the shape-retaining hose body 2 and has the thread-like flocks 7a erected on the outside in a brush shape.
[0010]
The flocked resin layer 6 in which the yarn-like flocks 7a are erected is prepared in advance as a tape-like material in which, for example, a synthetic fiber is woven in a net shape and the flock-like flocks are cut at the tip, and then impregnated with resin. After the hose body 2 is completed, it is fixed by bonding or the like while being spirally wound so as to cover the entire surface. Of course, any suitable material can be used as long as it is a sheet-like material provided with the thread-like flocks 7a in a brush shape.
[0011]
Further, the brush-like thread-like flocks 7a erected from the flocking resin layer 6 have a strength that does not buckle even when receiving the weight of the shape-retaining hose body 1 in a state where fire-extinguishing water is filled.
[0012]
FIG. 2 is an example of a fire hydrant device in which the fire-extinguishing shape holding hose of the present invention is used. In this fire hydrant device, the shape retaining hose 1 of the present invention with a nozzle 12 is housed in a state wound around a hose reel 14 in a door 11 of a cabinet case 10 installed on a wall of a tunnel or the like.
[0013]
In the event of a fire, the door 11 is opened as shown to expose the hose reel 14 installed inside the door in front of the cabinet case 10 and pull out the shape retaining hose 1 with the nozzle 12 portion.
[0014]
When the shape retaining hose 1 of the present invention is pulled out from the hose reel 14 in this way, sliding friction occurs between the hose surface and the road surface, but the shape retaining hose 1 of the present invention is on the surface as shown in FIG. By moving the tip of the brush-like flocking provided while in contact with the road surface, it becomes a so-called cilia movement state, and it is pulled out with a very small force compared to the sliding friction when the surface of the conventional hose directly contacts the road surface. be able to.
[0015]
Similarly, when the hose used after fire extinguishing is wound around the hose reel 14 and stored, it can be stored with very little force.
[0016]
Furthermore, in the tunnel, fire hydrant devices 10 as shown in FIG. 2 are installed at intervals of, for example, 50 meters, and the length of the hose required in this case is 30 meters on the left and right. When the shape retaining hose 1 of the present invention is used for such a fire hydrant device 10 of a tunnel, if the shape retaining hose 1 of the present invention is used with the same force when the conventional shape retaining hose is pulled out to 30 meters, for example 40 meters. Can be pulled out as long as possible.
[0017]
For this reason, the installation interval of the fire hydrant device 10 in the tunnel can be increased to, for example, 60 meters by using the shape-keeping hose 1 of the present invention. As a result, the number of fire hydrant devices installed in the tunnel is reduced and installed. Costs can be reduced and maintenance can be facilitated.
[0018]
FIG. 3 shows another embodiment of a fire-fighting shape retaining hose 1 according to the present invention. In this embodiment, a loop-shaped flocking 7b is formed in a brush shape on the outside covering the entire surface of the shape retaining hose body 2. It is characterized in that an upright flocked resin layer 6 is provided. If the loop-like flocks 7b have the same thickness as the yarn-like flocks 7 shown in FIG. 1, the rigidity is high, so that the density of the flocks can be lowered. The other configuration is the same as that of the embodiment of FIG.
[0019]
Of course, the shape of the flock provided in the shape-retaining hose 1 of the present invention can take an appropriate shape other than the thread shape or the loop shape.
[0020]
FIG. 4 shows another embodiment of the present invention. In this embodiment, a part of the surface of the shape-retaining hose body 1 is covered with a brush-like flock 7 and a brush-like flock is provided. 7 is covered with a spiral. As specific examples of the flocks 7, the flocked resin layer 6 in which the filamentous flocks 7a of FIG. 1 are erected are spirally wound, or the flocked resin layer 6 in which the looped flocks 7b of FIG. 3 are erected are spirally wound. It is a thing.
[0021]
Thus, by providing the flocks 7 in a spiral shape on the surface of the shape-retaining hose body 1, the manufacturing cost can be reduced as compared with the case where it is provided on the entire surface. Further, when the flocks 7 are partially divided and contacted with the road surface, dust, pebbles and the like that have fallen on the road surface accumulate on the exposed portions of the shape-retaining hose body 1 and enter the flocks 7 to cause sliding friction resistance. There are few things.
[0022]
As an embodiment in which the hair transplantation 7 is provided on a part of the surface of the shape retaining hose 1 in this way, in addition to providing the hair transplantation 7 of FIG. 4 in a spiral shape, a ring shape, a slit shape provided separately in plural in the longitudinal direction, etc. Including the formation of appropriate partial flocking.
[0023]
In the above embodiment, the case of using the shape-keeping hose provided with the brush-like flocking of the present invention on the surface of the tunnel fire hydrant device is taken as an example. If it is a place that is relatively smooth and has a ciliary movement with respect to the movement of the hose, use a fire hydrant at any facility or place, and when pulling out a shape retaining hose other than the fire hydrant as it is Applicable.
[0024]
Further, the present invention includes arbitrary modifications that do not impair the advantages and features thereof, and is not limited by the numerical values shown in the above embodiments. Furthermore, although the said embodiment uses the flocking of the resin material, it is not restricted to this, A cloth material may be sufficient if it is a brush-like flocking.
[0025]
【The invention's effect】
As described above, according to the present invention, a part or all of the surface of the shape-retaining hose body is covered with brush-like flocks, so that the sliding movement when the hose is pulled out is a cilia movement. As a result, the pulling force is reduced, and even a long hose can be pulled out with a small force, and the hose can be pulled out long even with the same pulling force. Of course, the hose drawn out for a long time can be stored with a small force.
